So-called handheld viewers are used to make invisible IR or UV laser radiation visible. They function similar to display cards and conversion screens, with the exception that they may not be held directly into the laser beam.
Making Radiation Visible
LASER COMPONENTS offers a variety of UV/IR viewers that make radiation from 350 nm to 1550 nm visible to the human eye.
These standard units cover the wavelength range from approximately 350 nm to 1350 nm. In addition, there is a version available for the IR range (up to 1550 nm). This enables the selection of an appropriate device to match the application. All viewers come in a transport case with batteries included.
UV/IR viewers are used in research, development, production, and medical technology. Typical applications include beam adjustment or the detection of undesired scattering.
